Videotactic and audiotactic assisted surgical methods and procedures
First Claim
1. An endoscopic procedure viewing system, the system comprising:
- (a) providing pre-operative scan data representative of a patient'"'"'s body or part of a patient'"'"'s body;
(b) creating a computer-generated reconstruction of an internal patient volume from the pre-operative scan data and/or digital atlases;
(c) creating a computer-generated real-time image from a camera on an endoscope of at least a portion of the internal patient volume;
(d) causing a computer to overlay the computer-generated real-time image and the computer-generated reconstruction with substantial spatial identity and substantial spatial fidelity; and
(e) creating computer-generated visual feedback, the computer-generated visual feedback showing position, trajectory and movement of the endoscope in a substantially real-time fashion on the overlay of the computer-generated reconstruction.

Abstract
The present invention provides video and audio assisted surgical techniques and methods. Novel features of the techniques and methods provided by the present invention include presenting a surgeon with a video compilation that displays an endoscopic-camera derived image, a reconstructed view of the surgical field (including fiducial markers indicative of anatomical locations on or in the patient), and/or a real-time video image of the patient. The real-time image can be obtained either with the video camera that is part of the image localized endoscope or with an image localized video camera without an endoscope, or both. In certain other embodiments, the methods of the present invention include the use of anatomical atlases related to pre-operative generated images derived from three-dimensional reconstructed CT, MRI, x-ray, or fluoroscopy. Images can furthermore be obtained from pre-operative imaging and spacial shifting of anatomical structures may be identified by intraoperative imaging and appropriate correction performed.

13. An endoscopic viewing system for providing visual and audible feedback, the system comprising:
-
(a) providing pre-operative scan data representative of a patient'"'"'s body; (b) creating a computer-generated reconstruction of an internal patient volume from the pre-operative scan data and/or digital altases, the computer-generated reconstruction identifying at least one feature of interest within the overall volume; (c) creating a computer-generated real-time image from a camera on an endoscope of at least a portion of the internal patient volume, the computer-generated real-time image further including at least one trackable point, the at least one trackable point movable in real-time with respect to the overall volume; (d) causing a computer to overlay the computer-generated real-time image and the computer-generated reconstruction with substantial spatial identity and substantial spatial fidelity; and (e) creating computer-generated visual feedback, the computer-generated visual feedback showing movement of the endoscope in a substantially real-time fashion on the overlay of the computer-generated reconstruction; (f) causing the computer to track the at least one trackable point with substantial positional fidelity to the computer-generated real-time image; and (g) creating computer-generated audible feedback, the computer-generated audible feedback describing movement of the at least one trackable point with respect to the at least one feature of interest. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
